Depth: | 230 m |
Drilling Angle: | 90 ° |
Drilling Method: | Core drilling |
Date Drilled: | 01. Jan 1989 |
Type: | helicopter or offroad vehicle, 0.5-1 hour walk. |
Permafrost Thickness: | >250 m |
Permafrost Zone: | Discontinuous |
Vegetation: | Without vegetation. Nival zone (highmountain desert). |
Landform: | Upper Pleistocene and Holocene morainic complex and hillside deposits. First moronic complex with buried ice is Holocene age and connected with Little Ice Age. Position (weight) of moraines with buried ice is taken about 7% from total area of surface glaciation in this place. Second complex is formed by fragments of frontal moraines Earlier Holocene and Upper Pleistocene glaciation with development ground ice, which forming of permafrost texture. Surface of moraine Q4. |
Lithology: | Site is belonging a zone of Hercynian and Caledonian folding of Tien Shan. At the ancient granite-gneiss base the sedimentary rock of Riphean-Vend is unconcordant bedding. Thickness both of suites reaches more than 700 m. Upper layer composed of boulders and detritus with silt filler. Ice content of permafrost is 15-20% and uniform through the section. Next type of superficial cover is a slopes deposits. Predominant is schist talus has a 4-7 m thickness. Ice content is reach 25-30%. |
Morphology: | Western slope of Ak Shiyrak Range. Glacial relief. Large glacier circuses with modern glaciers, steep ridges and flatness surfaces of watersheds. |
